Banks have started to implement behavioral biometrics more and more as it is seamless for customers and helps to better detect fraud; behavioral biometrics firms like BioCatch has provided banks with the type of security they like, customers cannot see if but it also is harder for criminals to spoof; BioCatch reviews more than 5 billion transactions per month and has about 60 million users in their system; another reason banks love this type of security is the privacy regulations are not as strict, the data is not personally identifiable and is based on type of actions.
